DH and i are going for our annual F&WF trip sept 26th (27yo DD and i went in may).
i think adult vacations are MUCH more leisurely...i lay by the pool (margarita in hand) quite a bit, we play pinbal in the MK arcade, ,inigolf, stroll over to DHS just for TSM FPs and to watch a few street shows, or to EPCOT for a grey goose slushie, maybe soarin', and browsing thru shops (LOVE morrocco!), eat and shop offsite some days.
we make very few ADRs, and just decide our plans depending on our mood - very difficult to do with children, where days are filled with go-go-go, ropedrops, going on every attraction and feeling like down time is wasted time
.
btw, we are meeting up with about 4 other couples this trip - all of whom are sans children for the trip.
so many families come home from a WDW trip saying they need a vacation from their vacation - we come home rested and refreshed
(btw, i've been all over north america, and quite a bit of euurope - WDW is where we can just relax).
